Drain pump

DIY. Call someone if the machine is hard-wired and you are not comfortable at the breaker, or if the sump itself is cracked.

Check, in this order

1. Clear the filter at the bottom first — food debris there produces exactly this symptom and costs nothing.
2. Check the drain hose to the disposer or standpipe for a kink, and that the disposer knock-out plug was removed if it was newly installed.
3. Listen during the drain step: a hum with no water movement points at a seized pump; silence points at power or the control.

Before you open anything

• Cut power at the breaker — a dishwasher is usually hard-wired, not plugged in.
• Close the water supply valve under the sink.
• Bail out the standing water before tilting anything.

Tools

• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• Shallow pan and towels ($0) — Residual water always comes out, even after draining.
• Slip-joint pliers ($12) — Hose clamps and inlet filter screens.
• Flashlight ($0) — Boot, sump and pump housings are dark.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Bail the standing water and remove the lower rack and filter.
2. Pull the machine out far enough to reach the underside; some models are serviced from below.
3. Photograph the wiring and hose clamps before releasing anything.
4. Release the pump from its mount, swap it in, and reseat every clamp.
5. Restore power and water, then run a rinse cycle watching for leaks before pushing it back.

How you know it worked. A full drain within the drain step, no standing water at cycle end, no drip under the machine.

Worth fixing? Weigh it - this part is a meaningful share of a new machine. Part $19.99–$74.95 against $279.87 for a new machine (26.8%).Part cost only. A service call adds a regional diagnostic fee plus labour.

Thermostat

DIY once tested. If the heating element itself is open, treat that as the repair instead.

Check, in this order

1. Run the kitchen tap hot before starting a cycle — a dishwasher fed cold water often never reaches temperature.
2. Check the household water heater setting.
3. Test the thermostat for continuity before replacing it.

Before you open anything

• Cut power at the breaker.

Tools

• Multimeter ($25) — Confirm continuity before replacing an electrical part.
• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• Flashlight ($0) — Boot, sump and pump housings are dark.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Access the thermostat at the sump or lower panel.
2. Photograph the terminals, then release them.
3. Fit the replacement and confirm it seats flush against its mount.

How you know it worked. Dishes are hot at the end of the cycle and plastics dry noticeably better.

Control panel

DIY once the board is ruled out.

Check, in this order

1. Note whether some buttons work and others do not — partial response points at the panel, total silence at the board.
2. Check the ribbon connection to the board before replacing the panel.

Before you open anything

• Cut power at the breaker.

Tools

• T20 Torx driver ($7) — Some control and door assemblies use Torx rather than hex.

The repair, in order

1. Open the inner door panel.
2. Photograph the ribbon and harness.

Detergent dispenser

DIY.

Check, in this order

1. Check nothing in the upper rack is blocking the flap from opening.
2. Look for hardened detergent gumming the hinge.
3. Confirm the wax motor releases — the cup should be open at the end of a cycle.

Before you open anything

• Cut power at the breaker.
• Open the door fully and support it.

Tools

• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• T20 Torx driver ($7) — Some control and door assemblies use Torx rather than hex.

Circulation pump

Borderline DIY. It is a big strip-down; if the sump seal will not seat cleanly, get a technician before you flood the floor.

Check, in this order

1. Spin both spray arms by hand — if they are blocked or clogged, wash pressure fails without any pump fault.
2. Clear the spray-arm holes with a pin and re-run before condemning the pump.
3. Listen: a circulation pump that is running but not moving water sounds normal but leaves dishes dirty.

Before you open anything

• Cut power at the breaker.
• Close the water supply valve.

Tools

• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• 5/16" nut driver ($8) — Cabinet and bracket screws on most front-load machines are 5/16" hex.
• Shallow pan and towels ($0) — Residual water always comes out, even after draining.

• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Remove the lower rack, filter and spray arm.
2. Photograph the sump wiring before disconnecting.
3. Release the pump housing, swap the assembly, and reseat the seal squarely.
4. Run a full cycle and check underneath for leaks.

How you know it worked. Dishes come out clean and the spray arms turn strongly through the wash.

Control board

Get a technician to confirm before buying a board — it is the most expensive part and the most misdiagnosed.

Check, in this order

1. Rule out the latch switch, the panel and the power supply first — all are cheaper and all present as a dead machine.
2. Inspect the board for scorching or swollen capacitors.

Before you open anything

• Cut power at the breaker.
• Photograph every connector before removing any.

Tools

• T20 Torx driver ($7) — Some control and door assemblies use Torx rather than hex.
• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• Multimeter ($25) — Confirm continuity before replacing an electrical part.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Locate the board behind the lower access panel or in the door.
2. Transfer connectors one at a time against your photographs.
3. Reassemble the access panel, restore power, and run a short cycle to confirm the controls respond without an error.

How you know it worked. Normal start-up and a completed cycle.

Door seal

DIY.

Check, in this order

1. Run a cycle and watch where the water actually appears — door face means the seal, under the machine means plumbing.
2. Inspect the gasket for tears, hardening, or a section pushed out of its channel.

Before you open anything

• Cut power at the breaker.

Tools

• Thin putty knife ($5) — Releasing clips without marking the cabinet.
• Flashlight ($0) — Boot, sump and pump housings are dark.
• Shallow pan and towels ($0) — Residual water always comes out, even after draining.

The repair, in order

1. Peel the old gasket from its channel, noting the orientation.
2. Clean the channel completely.
3. Press the new gasket in from the centre of each run outwards so it cannot stretch short.

How you know it worked. A full cycle with no water on the door face or the floor.

Door latch

DIY.

Check, in this order

1. Confirm the door closes firmly and the strike is aligned.
2. Test the latch switch for continuity in the closed position — a dishwasher will not start on a failed switch even though the door feels shut.

Before you open anything

• Cut power at the breaker.

Tools

• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• T20 Torx driver ($7) — Some control and door assemblies use Torx rather than hex.
• Multimeter ($25) — Confirm continuity before replacing an electrical part.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Open the inner door panel to reach the latch assembly.
2. Photograph the switch wiring, swap the latch, and check alignment before reassembling.
3. Reassemble the inner door panel, restore power, and confirm the door latches and a cycle starts.

How you know it worked. The cycle starts on a normal close, every time.

Door hinge

DIY but two-handed. Get help holding the door.

Check, in this order

1. Open the door halfway: it should hold position rather than fall.
2. Look for a snapped hinge cable or a stretched spring at either side.

Before you open anything

• Cut power at the breaker.
• The door is heavy and will drop when the hinge cable is released — support it.

Tools

• 5/16" nut driver ($8) — Cabinet and bracket screws on most front-load machines are 5/16" hex.

Wash sensor

DIY.

Check, in this order

1. Clean the sensor window in the sump — a filmed-over sensor reads every load as clean.
2. Confirm the filter is clean, since debris coats the sensor.

Before you open anything

• Cut power at the breaker.

Tools

• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• Flashlight ($0) — Boot, sump and pump housings are dark.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Remove the filter and locate the sensor in the sump.
2. Photograph the connector, swap the sensor, and refit the filter.
3. Reassemble the filter and spray-arm area, restore power, and run a short cycle to confirm the dishwasher fills and washes normally.

Heating element

DIY once tested with a multimeter.

Check, in this order

1. Confirm the thermostat isn't the actual fault first — test the element itself for continuity before replacing it.
2. Look for a visibly broken or blistered section of the element.
3. Run the tap hot before starting a cycle to rule out cold-fill as the cause.

Before you open anything

• Cut power at the breaker — a dishwasher is usually hard-wired, not plugged in.
• Let the element cool before touching it.

Tools

• Multimeter ($25) — Confirm continuity before replacing an electrical part.
• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• Flashlight ($0) — Boot, sump and pump housings are dark.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Remove the lower rack and access the element at the base of the tub.
2. Photograph the wiring terminals before disconnecting.
3. Test the element for continuity with a multimeter to confirm before ordering a part.
4. Swap the element and reconnect the terminals exactly as photographed.
5. Run a full cycle and confirm the water and dishes are hot at the end.

How you know it worked. Dishes and the interior are hot to the touch at the end of a cycle, and plastics dry properly.

Lower wash arm

DIY.

Check, in this order

1. Spin the lower arm by hand with the rack out — it should turn freely with no drag or wobble.
2. Check for cracks near the hub and jet holes that look enlarged or blown out.
3. Clear the jet holes with a pin before assuming the arm itself has failed.

Before you open anything

• Cut power at the breaker.

Tools

• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• Flashlight ($0) — Boot, sump and pump housings are dark.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Remove the lower rack to access the arm.
2. Lift the arm off its hub, checking the hub and bearing ring for wear.
3. Snap the new arm onto the hub until it seats and spins freely.
4. Run a cycle and confirm even spray from the lower jets.

How you know it worked. The lower arm spins freely and sprays evenly through a full cycle.

Spray arm

DIY.

Check, in this order

1. Spin the arm by hand — it should turn freely with no wobble or drag.
2. Look closely for hairline cracks near the hub and jet holes that are enlarged or broken through.
3. Clear the jet holes with a pin first — clogged jets mimic a cracked or worn arm.

Before you open anything

• Cut power at the breaker.

Tools

• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• Flashlight ($0) — Boot, sump and pump housings are dark.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Lift the arm off its hub — most spray arms simply lift free once the rack is out.
2. Inspect the hub and bearing ring for wear alongside the arm itself.
3. Snap the new arm onto the hub until it seats and spins freely.
4. Run a cycle and confirm even spray from every jet.

How you know it worked. The arm spins freely through a full cycle and every jet sprays evenly.

Door spring

DIY but two-handed — get help holding the door while the spring is off.

Check, in this order

1. Open the door partway — it should hold at any angle; a door that drops or feels weak points at a stretched or snapped spring rather than the hinge itself.
2. Check both springs (left and right) — a spring failing on only one side makes the door drop unevenly.

Before you open anything

• Cut power at the breaker.
• The door is heavy and will drop suddenly when a spring is released — support it before disconnecting anything.

Tools

• 5/16" nut driver ($8) — Cabinet and bracket screws on most front-load machines are 5/16" hex.
• #2 Phillips screwdriver ($6) — Panel and bracket screws.
• Phone camera ($0) — Photograph connector positions before unplugging anything.

The repair, in order

1. Support the door in the open position.
2. Remove the side panels to reach the spring and its cable.
3. Replace springs in pairs when either side shows wear, and re-tension evenly.
4. Release the support and check the door holds at every angle before closing it fully.

How you know it worked. The door holds firmly at any angle and closes without dropping or slamming.
